Be it known ilmt LEWIS D. COR'IRIGHT,

of Hyde Park, Cook county, Illinois, have invented a new and useful Improvement in Me- 5 tallie Rootingllates or Shingles, of which the following is a true and exact description, due reference beinghad to the accompanying drowings, which form part hereof.

My invention relates to the construction of to whet nre generally known as metallic shingles for roofing, these shingles consisting of smell metallic plates adapted to be secured to the boarding of a roof ny nailing in the some way as wooden shingles or slates.

The object of my invention is to provide alock-joint and gutter l'or such inetel shingles by which the entrance of water through the vertical joints onto the boarding of the roof 7 will be effectually prevented, while at the some t me the vertical edges of adjoining shin gles are properly united and aligned.

.Reference being now had to the drawings which illustrate my invention, Figure 1 is it perspective view of a number of my improved shinglcsus applied to n roof, and Fig. 28 end view 0! two of my shingles interlocked and secured to the roof-boarding.

A A A A are my improved shingles, the opposite vertical edges of which are bent, as 30 shown at B and C. The edge C oi my shingle is bent so, as to form the square hook I) d out of the double thickness of the metal, and the sheet is then carried outward on the plane of the main surface A to n point some dis tonne beyond the point (I of the hook, where an upward bond is made in the metal to form the projection F, the metal being carried snf liciently beyond this projection to form at nnillug-flange, G. The edge 13 of my shingle is bent Upward at .1, so as to lit or hook overthe projection i and terminates in anoth r upward bend or hook, 1,:1duptcd to tit under the downwnrdly projecting point (I of the hook K represents the supporting-boards to which the shingles are nailed; ll, a nail for securing the nailing-flange (i to the support, while L is the usual projection formed in the bottom of the center. of each shingle to accommodate the elevated seam of the lower shingles and so allow the upper plates to rest closely upon the lower ones.

In laying my shingles, constructed as shown in the drawings, the Iel'thand-shingle is first secured to the roof by the mailing -flange G. The hook I of the next shingle to the right is then inserted underthie point d, and the shingle then turned downward on this edge as e hinge until the projection J fits over the projection l! of the lower shingle, and the righton hand shingle then lying fist upon the roof is nailed down in the same way as the one to the 7 left. The natural spring of the metal will causethc bottom of the hook I to fit tightly against the point d and the top of the projeotion J to press upon the top edge of F, so that my construction insures two points or rather lines of close contact in the sidejoints of my shingles. The large open space E, formed in the edge 0 by the hook D d and the projee tion h, and closed by thocdge B of the adjoining interlocked shingle, affords an ample nndfree passage or guttgr for any water that may enter the scam formed by the pointd and. the hook I, the projection F serving as a dam to prevent the water getting onto the nettling-linngc, and thence to the boards K. Asis shown, the gutter E in each case opens freely upon the center of a shingle in the row below.

it is evident that my improved seam and gutter can be used with oblique n's well nsvertirnl ioinls, and of course the shape of the hook I) (l may be varied, the square shape shown being, however, preferred by me. The proportions of the various parts of my some may also be varied; but in all cases the distnnce between the point d and the projection l must be sulliciontly great to allow of the insertion of the bent edge B by the folding operation described. J

Having now described my invention, 'WhetI claim as new, and desire to secure by Letters Patent, is-

1. Ass new article of manufacture, metallic roofing-shingles having an edge, 0, provided with a hook, I), having it downwardlyprojectiug point, d, and a "projection, and ilnngel beyond paid point,and an opposite edge, B,' having a projection, J, and hook I, back of bh ih te rlocked edges of the adjoifiing adapted to interlock with the pointd and proshingle and form an unobstructed gulater subjection Ff'of a similar shingle. stantially as; shown and describ'd.
